ることにより連結されている。Generally, when many solid materials such as steel pipes are three-dimensionally connected to construct a three-dimensional truss, ball joints are often used to connect single materials, but single material and ball joints are single materials. A connector is previously installed in a nose cone protruding from the end, and the connector is connected by being screwed into a screw hole on the surface of the ball joint.
当出願人はこのような構造のトラスの継手構造を実願昭
62−108628号に於いて既に出願している。The present applicant has applied for a joint structure of a truss having such a structure.
